Gigabeat S/i.MX31: Take care of an interrupt priority inversion that can happen during PCM callback lockout when DVFS switches frequecies during the lockout, preventing a thread from unlocking the callback until DVFS finishes, causing an SSI FIFO underrun. Hadn't thought of an acceptable way to deal with it before.
